Below are some basic troubleshooting tips for common problems. If you try
the tips below and still have issues, try asking on the
forum
for help.
Drivers
Ensure that you are using the latest reference drivers available for your
video card. Often drivers that shipped with the card on a CD or came
stock with the system have issues/bugs.
Choosing a Rendering Backend
For broad compatibility, OpenGL is generally advisable; however, some
cards run better under Direct3D. Direct3D is good on systems with
limited memory or weaker hardware.
You can try both to see which one works better on your system. If you own
a Voodoo Graphics card, the Glide backend will be the most performant
one for you (unless you need to play in a window).
A (loose) suggested renderer list by vendor:
Nvidia / ATI: OpenGL
3dfx: Glide
S3 / Matrox / Other: Direct3D
Configuration
All settings can be manually modified in settings.ini
located in the application's configuration folder. This can be quickly
found using the setup tool and opening View -> Config
Folder. Some settings can only be tweaked there.
Choose a resolution that matches your desktop resolution. Avoiding the
resolution change can prevent problems with buggy video drivers. If this
still fails, try a small well-known resolution like 640x480 or
800x600.
It's generally best to avoid manually setting the bit depth/refresh rate.
If required, these can be configured via DISPLAY_BITDEPTH
and DISPLAY_REFRESH_RATE under the [Display]
section of settings.ini.
